A few key parts of the Angular 8 architecture are as follows -

• Angular 8 MetaData - Metadata in Angular version 8 is used to decorate a class for the configuration of the expected behavior of the class.
• Angular 8 DataBinding - Data Binding is used to BIND the data from the component to the template.
• Angular 8 Components - Angular Components are building blocks of all Angular applications. Every angular application is made up of one or more Angular Components. It is basically a plain JavaScript or Typescript class along with an HTML template and an associated name.
• Angular 8 MODULES - It is a collection of related features. Angular 8 Module groups multiple components and services under a single context.
• Angular 8 Services - Services are nothing but plain and simple Typescript or JavaScript classes that provide very specific functionalities. They help us do a single task in the best possible WAY so that code reusability is ACHIEVED. Rather than writing a functionality inside a component, separating it into a service makes it reusable in other components as well.
• Angular 8 Templates - Angular 8 template is a superset of HTML (HyperText Markup Language). It includes all the features of HTML and gives us additional features to bind the component data into the HTML and to dynamically generate the HTML DOM ELEMENTS.
